@ -95,7 +95,6 @@ While I've been successfully using 'sdtui' for many years now, some issues
should be addressed before including the software in regular Linux and/or
BSD distributions:
- The tab bar doesn't handle overflows well in the TUI.
- The GUI is awkward to configure.
- Lacking configuration, standard StarDict locations should be scanned.
